How to enter flash mode

Hold Power + Volume Down while the phone is turned off. This will make the phone boot into fastboot mode

Installation

You will need to unlock the bootloader in order to be able to flash anything onto the phone.

Installing TWRP before doing anything else is recommended, as it makes dealing with the phone easier later on, and allows for quick restoration by taking backups of /system and /boot, then flashing them back in order to restore the device to its original state. Note that this method has only been tested with LineageOS, and running its installation ZIP in TWRP after restoring the backup was necessary to get it to boot, otherwise it would just keep loading forever.

NOTE: Flashing to the system and boot partitions will wipe the Android core but will leave all apps and user files. If you want to be able to easily restore Android, it is recommended to backup both partitions using the method above.

WARNING: Flashing to the data partition will erase all user data! Make sure all important files are backed up before flashing.

Pre-built Images

Follow the installation article to download image files.

Replace <image> with the name of your image where necessary.

Once downloaded, decompress the images with xz:

$ xz -d <image>-xiaomi-scorpio.img.xz
$ xz -d <image>-xiaomi-scorpio-boot.img.xz

Once decompressed, you may flash the main image to either:

/system: ~3.2 GB. Will allow you to keep the main part of your existing Android installation as well as your data.

$ fastboot flash system <image>-xiaomi-scorpio.img

/userdata: Extends close to the remaining size of your storage. Will wipe your Android installation along with your data.

$ fastboot flash userdata <image>-xiaomi-scorpio.img

Then you may either flash the boot image:

$ fastboot flash boot <image>-xiaomi-scorpio-boot.img

or boot it directly without flashing:

$ fastboot boot <image>-xiaomi-scorpio-boot.img

Manual Build

To build your own image, follow the pmbootstrap article.

Once you reach the flashing step:

Flash the rootfs:

$ pmbootstrap flasher flash_rootfs

NOTE: If you need more space in the rootfs, you can also flash to the data partition by appending --partition data to this command. More information about the partitions can be found in the prebuilt images section above.

Flash the kernel and initramfs to the boot partition:

$ pmbootstrap flasher flash_kernel

You can also avoid flashing them and instead, boot the kernel directly:

$ pmbootstrap flasher boot

Feature	Components	Status
USB	TI TUSB320L (extcon) PMI8996 SMBCharger (OTG supply)	Y	SMBCharger OTG VBUS driver not upstream.

GPU	Adreno 530¹	Y
WiFi	QCA6174a	Y
Bluetooth	QCA6174a	Y
Modem	MSS¹	P	Sending and receiving SMS works. Mobile data will require a driver for IPA. Calls have not been tested, and while it might be technically possible to make and receive calls, it will not be of much use since modem audio routing hasn't been managed yet.
GNSS	MSS¹	N	requires PDS support in gpsd
NFC	NXP PN548	Y
IR Transmitter	PM8994 LPG²	Y
Audio Codec	WCD9335 (Headphones, earpiece, microphones) TAS2555 (Speaker)	P	Speaker codec will require a driver.
Video Codec	Venus¹	Y	Tested with `gst-launch-1.0 videotestsrc ! videoconvert ! v4l2vp8enc ! queue ! v4l2vp8dec ! xvimagesink`
Battery	PMI8996 SMBCharger/Fuel gauge² SMB1351²	P	Fuel gauge works. Charger can reach its maximum current at 5V. Faster charging (9V) will require extra handling in the PMI8996 SMBCharger driver, and for better efficiency (and possibly even faster charging) a new driver for SMB1351.
Rear Camera	Sensor: Sony IMX318 Lens Actuator: Asahi Kasei Microelectronics AK7375	P	Sensor has a basic driver with support for 3 modes and analogue gain control.
Front Camera	Sensor: Sony IMX268	N	Needs a driver.
Sensors	SLPI/SSC^1,2 Gyroscope/Accelerometer: LSM6DSM Magnetometer: AK09915 Pressure: BMP280 Proximity + Light: CM36686	N	Work in progress SSC driver.
Touchscreen	Atmel MaxTouch	Y
Touchkeys	Cypress StreetFighter	Y
Fingerprint Reader	FPC1020	N	Work in progress fingerprint subsystem and driver. Currently not supported by libfprint due to its small resolution of 192x56. The new sigfm algorithm implementation may change this, however.
Buttons	TLMM^1,2/PM8996 GPIO² (Home, Volume Up) PM8994 PON/RESIN² (Power, Volume Down)	Y
Haptics	PMI8996 Haptics²	Y	Driver not upstream yet.

Known issues:

~~The display comes up blue after initialization sometimes. Rebooting makes it work usually.~~ This issue has not appeared since MSM DRM was set to be compiled as a module. Should be completely resolved with the addition of an interconnect driver.
~~System locks up when accessing memory intensively. This might be caused by writing to a protected area of memory.~~ Adding this reserved memory region fixed it.
~~System crashes when modem and ADSP get powered up at the same time.~~ Fixed temporarily through pmaports!2283.
~~USB VBUS turns off instantly when a USB device is plugged into an already plugged in OTG adapter. For now the OTG adapter must be plugged into the phone with the USB device plugged into it already.~~ Fixed.
WiFi range is bad. This is due to lack of board firmware. Supplying board firmware made from the vendor firmware for the downstream QCA_CLD driver makes it lose all APs in a scan as soon as an attempt is made to connect to one of them, which means it is impossible to connect. Fixed in pmaports!3271.
